ALMA View of the Galactic Center Minispiral: Ionized Gas Flows around Sagittarius A

We have observed the "Galactic center minispiral (GCMS)" in the H42 recombination line as a part of the first large-scale mosaic observation in the Sagittarius A complex using Atacama Millimeter/submillimeter Array (ALMA). We revealed the kinematics of the ionized gas streamers of the GCMS...
